两种记忆状况组来自于参与加拿大维多利亚纵向研究(VLS)的老年人原样本。一种是未受损伤的控制组(NIC),另一种是轻度记忆损伤组(MMD)。在基线水平和纵向水平上(即5次追踪或12年)比较了他们在日常生活中对记忆补偿技术的使用。我们使用多水平模型(以年龄和教育水平为协变量)来检验基线水平的差异和长期的变化模式。基线的结果表明MMD组被试报告了近期在日常生活中使用记忆补偿策略方面有更大的增长。纵向的结果表明记忆补偿的使用在12年中具有明显的稳定性,但是与努力相关的补偿机制存在显著组间差异。教育水平这一协变量(可认为是潜在的认知储备指标)和三种记忆补偿策略随时间的不同变化相关。
The two memory status groups were from the original sample of seniors who participated in the Villar Victoria longitudinal study (Canada). One is the undamaged control group (NIC) and the other is the mild memory impairment group (MMD). Their use of memory compensation techniques in their daily lives was compared at baseline and longitudinal levels (ie, 5 tracings or 12 years). We used a multi-level model (age- and education-level covariates) to test for differences in baseline levels and long-term patterns of change. Baseline results showed that subjects in the MMD group reported a greater increase in the use of memory compensation strategies in daily life in the near future. Longitudinal results indicate that the use of memory compensation has significant stability over 12 years, but there are significant group differences between effort-related compensation mechanisms. The level of education, a covariate (which could be thought of as a potential cognitive reserve indicator), correlates with changes in three memory compensation strategies over time.
